一般描述

微粒或乳胶珠，通常称为聚苯乙烯微粒，是带负电的胶体颗粒。微粒是通过苯乙烯在受控条件下的聚合反应制备的。反应的有利环境诱导自发聚结珠的形成。微粒或乳胶珠以由聚合物颗粒与水组成的水溶液提供。聚苯乙烯′在 589 nm 处的折射率为 1.5905，在 486 nm 处为 1.602。

应用

微粒或乳胶珠用于多种应用，如：
  • 电子显微镜。
  • 细胞计数器校准。
  • 免疫诊断学，尤其是乳胶凝集试验和
  • 吞噬细胞研究。

The unusual properties of nanocomposites are commonly explained by the structure of their interphase. Therefore, these nanoscale interphase regions need to be precisely characterized; however, the existing high resolution experimental methods have not been reliably adapted to this purpose. Electrostatic

Hollow silica and silica-polymer spheres with diameters between 720 and 1000 nanometers were fabricated by consecutively assembling silica nanoparticles and polymer onto colloids and subsequently removing the templated colloid either by calcination or decomposition upon exposure to solvents.

Questions

1–2 of 2 Questions  

  1. Are the Microparticles based on polystyrene in a suspension sterile? Or is it possible to sterilize the microparticles?

    1 answer

    1. The polystyrene microparticles offered for sale are not sterile.

      Although autoclaving is a common method of sterilization, polystyrene microparticles are not autoclavable. Filter sterilization is also not a practical method. There are no protocols available for sterilizing polystyrene microparticles. From the remaining methods for sterilization, it should be possible to either sterilize in 70% ethanol for 30 minutes and then rinse away the ethanol with sterile water. For small batches, UV radiation would be another option.

  2. What is the composition of the "Aqueous Suspension." I want to use these in an exposure experiment, but must control for whatever the suspension is. Is it possible to get the exact details of its makup.

    1 answer

    1. The composition is water and polystyrene.
